Electroacupuncture Alleviates Postoperative Cognitive Dysfunction in Aged Rats by Inhibiting Hippocampal Neuroinflammation Activated via Microglia/TLRs Pathway

Figure 2

Effects of EA treatment on the levels of IL-1β, IL-6, TNF-α, and HMGB1 in the hippocampus. The hippocampal concentrations of IL-1β (a), IL-6 (b), TNF-α (c), and HMGB1 (d) of rats were measured on day 3 and day 7 postoperatively. The bars represent the mean ± SD. Five rats were included in each group. All of the results were compared at the same time point. ; versus the control group; versus the surgery control group; versus the surgery + drug group. 3 day and 7 day: operation group on day 3 and day 7 postoperatively, respectively.
